I have a 1999 Super Sport with the 5.7 Apex, Walter V-drive and PCM transmission. I purchased the boat in 2013 with 370 hours & completely stock. I plumbed it with auto ballast, tower, four blade prop, etc.. Currently has 402 hours and has been well maintained. It is a second boat and used mainly to surf and ski when we have guest at our cabin thus the low hourly usage.
A couple of weeks ago a friend was driving and he slammed the throttle taking the engine up to almost 5000 rpm for a few seconds before I yelled to pull it back. Did not stay @ 5000 rpm for more than a few seconds, only long enough for me to ask him to stop. Was a wee bit concerned, but did not to think too much about it as it was only a few seconds. About 30 minutes later we filled the ballast (2500#'s) and I jumped in to surf, one pass and no problems. Second run, stared to pull up and then the driver stopped. Said the boat started to pull, then the rpm's jumped and he felt that power was not going to the prop. Essentially the transmission slipping. I got back in the boat, emptied the ballast and headed home. Did fine going home, didn't push but didn't feel quite right. Checked all the fluids(no water in fluids and no leaks), took it back out for a drive and got a little slip when I accelerated hard out of a turn. Put the boat up for the day.
Last weekend I changed the transmission fluid with the mighty vac (no water in fluid, did not smell or look bad however did have fine particles in the bottom of the might vac) and changed the V-drive oil. Took it out for a test run and it didn't slip, but again didn't feel right as it didn't seem to have the same pep. Went out again with the kids on the tube and felt like I had one little hesitation out of a turn but that was all. I don't know if I am being paranoid which is skewing my feel, but I will say again I didn't feel like it had quite the acceleration as before.
With all that said, I have a few questions.
Could the acceleration up to 5000 RPM's be the cause of the slippage?
Or, could it have accelerated an issue that was already present? I have read the PCM transmissions are not the best, so I would not be surprised if this is the case.
Either way, at this point I am trying to figure out what is the best course of action.
Should I begin to look into a new transmission and if so, what should I consider while trying to maintain the stock rotation?
Or, do I go the rebuild route (I have heard they are expensive to rebuild and not the best option) and if so, who/where would I go in this scenario?
Lastly, I have done all the work mentioned above and have most tools to do the work, but is this something I leave to a mechanic?
Thanks in advance for your time and any recommendations.
Cheers,
Geoff
